How to DIY a 12v LiFePO4 Battery Pack From a 32650 LiFePO4 Battery Cell

/106 Comments/in /by

Nowadays, many rechargeable electrical appliances in life use lithium batteries, such as soft packs, cylindrical, rectangular and so on. Among them, cylindrical lithium batteries are divided into various models according to their size, such as the most common 18650, 22650, 32650 and so on. The number 18 in the model like 18650 indicates the diameter of the battery, 65 indicates the length of the battery, and 0 indicates that the battery is a cylinder.

The voltage of a single-cell lithium battery is generally 3.2V to 3.7v, and the voltage used by many electronic devices is 12V, so we need to use multiple lithium batteries to form a group to achieve 12v, and the lithium battery assembly also needs to be equipped with a protective plate.

The main purpose of the protection board is to play overload protection, short circuit protection, overheat protection, low voltage protection, overvoltage protection, battery balance, overcharge protection, etc., mainly to protect the battery from being damaged.

Since the capacity of a single battery is relatively small, 12 32650 lithium batteries are prepared, four are connected in series to form a group of 12V, and then three groups of 12V are connected in parallel to increase the capacity and voltage.

Assembling the battery requires the use of nickel tape, high temperature tape, and battery brackets.

Generally, the connection of lithium batteries is to use spot welding to bring the nickel to the point. If there is no spot welding machine, you can use sandpaper to polish both ends of the battery, and then you can use an electric soldering iron to weld.

Get the battery line, measure the voltage, and see if the capacity is the same. Don’t put the different ones together.

Then install the battery and battery holder and arrange them in a positive and negative order.

Then wrap the heat resistant tape around it.

Connect the batteries with nickel tape, a soldering iron will do without a spot welder. By the way, stick the protective plate on top of the tape.

For the effect of spot welding of nickel strips, it is necessary to distinguish which one is connected with which one, otherwise it will cause a short circuit.

Then solder the protection board and the plug. Generally, the protection board will indicate the connection method in detail, and it is enough to connect with wires.

If you feel that one plug is too few, you can add another one, and the 12V lithium battery is completed.

    An outstanding share! I have just forwarded this onto a colleague who has been doing a little research on this. And he in fact ordered me dinner due to the fact that I discovered it for him… lol. So let me reword this…. Thanks for the meal!! But yeah, thanks for spending some time to talk about this subject here on your internet site.
